Cross Connection Survey

The Illinois EPA mandates that municipalities conduct a survey of all water users to see who has a backflow preventative device connected to their water service. 

These are commonly called a RPZ (Reduced Pressure Zone).  All businesses should have one of the devices installed.  For residential water users, these devices are commonly installed with an in-ground lawn sprinkler system.   

The Village has decided to use an online survey format to comply with the IEPA regulations.  

Residents and business owners should go to to complete the survey.  If you are unsure whether you have an RPZ device, you may email a picture of your device to Public Works at or contact Public Works at 847-546-0962.
